Specification of Letters Patent. Patented J 11119 20, 1911.

Application filed March 28, 1911.

Serial No. 617,415.

To all whom it may concern:

Be it known that I, SAMUEL SHAPIRo, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMilk-Coolers, of which the following is a specification.

My invention relates to improvements in milk coolers, the object of theinvention being to provide a device of this character which will beespecially adapted for use at the farm or place of milking, and adaptedto promptly cool the milk before it is stored in the cans for shipment.In other words, this cooler is especially adapted to receive the bucketsof milk from the milking operation and eifectually cool the milk,permitting it to aerate during the cooling operation, and promptlychilling the milk so as to prevent spoiling.

A further object is to provide an improved cooler of this character ofextremely simple inexpensive construction, which compels the milk tomove through a circuitous path, requiring every particle of the milk tobe subjected to the cooling action for the same length of time andprovide an. apparatus which may be perfectly cleaned when the coolingoperation is over.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings: Figure 1, is a plan view illustrating myimproved cooler with the cover removed. Fig. 2, is a view in section onthe line 22 of Fig. 1, and Fig. 3, is a view in section on the line 3-3of Fig. 1.

My improved cooler comprises a bottom 1, having a plurality ofconcentric circular vertical walls 2 thereon forming a central circularchamber 3 and four annular chambers 4, 5, 6, and 7 respectively aroundthe same. Chambers 3, 5, and 7, are water chambers, and are preferablywider than the second and fourth chambers 4 and 6, which are milkchambers. Water chambers 7 and 5 are provided with vertical partitions 8and 9' respectively, and milk chambers 6 and 4 are provided withvertical partitions 10 and 11 respectively.

12 is a water supply pipe which projects up into water chamber 7 at oneside of partition 8, and is provided with a shield 13 to prevent thestream of water from passing upwardly, but compel the water todistribute itself in the bottom of chamber 7. A valve 14 controls theflow of water through pipe 12, and this water flows around chamber 7 tothe opposite side of partition 8. hen it reaches a predetermined levelin said chamber, it passes down through a pipe 15, which discharges intothe bottom of chamber 5 at one side of partition 9. The Water then flowsaround this chamber 5 to the opposite side of partition 9, and flowsdown through a pipe 16 into the bottom of chamber 3. Its normal outletfrom chamber 3 is through a pipe 17 into a discharge pipe 18, and theseseveral chambers 7 5, and 3, are each connected with a drain pipe 19,which connects with pipe 18, and is provided with a cook 20 normallyclosed.

It will be noted that the pipes 15, 16, and 17 project up into therespective chambers at a uniform level, so that the water will bemaintained in these several chambers at this level, and there will be acontinuous flow in the circuitous path described from the outer to theinner chamber. A dome shaped cover 21 normally closes the cooler, and isprovided centrally with a ventilator 22, which allows the animal gasesin the milk to escape. This cover 21 is provided with an opening 23above chamber 6 for-the reception of a funnel shaped screen 24 throughwhich the milk is poured into the chamber 6 at one side of partition 10.A cover 25 is provided to close the opening 23 when the screen 24 isremoved. A baffle ring 26 is supported in chamber 6 on suitable posts27, and is provided at intervals with openings 28. This bafile ring 26acts to retard the flow of the milk, and serves to more effectuallyseparate the colder milk below from the warmer milk above, renderingmore slowly the downward passage of the milk. A pipe 29 located belowthe cooler is connected by pipe couplings 30 with openings 31 in thebottom chambers 4 and 6, and is provided at its discharge end with afaucet 32 normally closed. The milk which enters chamber 6 flows throughthis pipe 29 into chamber 4, and flows upward through said chamber as ittakes the circuitous passage around the chamber by reason of thepartition 11, and escapes through pipe 33, which has an outlet end 34through temperature before escaping.

which the milk flows into a can 35. This can 35 is covered by anordinary screen 36 so that not only is the milkscreened as it enters thecan, but before it enters the can.

The milk which flows through the screen 24 is of course warm, anddisplaces the cooler milk in chamber 6 causing said cooler milk to passthrough pipe29. As the screen 2% is located at one side of partition 10,this warmer milk before it escapes through pipe 29, must pass all theway around chamber 6 and down to the lower portion of the chamber, suchmovement being baffled by the ring 26. The milk then flows through thepipe 29 into the bottom of chamber 4: at one side of partition 11, andflows all around said chamber to the opposite side of the partition, andrises to a point high-enough to overflow through pipe 23. It willtherefore be noted that all the milk which enters the funnel 24 musttake the same course, and therefore must receive the same reduction ofTo drain the chambers 4t and 6, it is simply necessary to open faucet32, when all the milk in these chambers will drain into the can 35. Thisdraining operation does not take place until the entire coolingoperation of the milk is ended, so that the capacity of the device isabsolutely unlimited. To thoroughly clean the cooler, couplings 30 maybe loosened to remove pipe 29, and this pipe may be thoroughly washedout or placed in boiling water, and access may be had to the entireinterior of the cooler to thoroughly scrub and clean the same.

Ventilator 22 is so arranged that its interior may be cleaned byinserting the hand into the same from inside the cover. The cooler maybe provided with suitable feet 37 or supported in any other approvedmanner.

lVhile I have set forth that I use water as a cooling agent in chambers3, 5, and 7, I would have it understood that the inven tion is notlimited to any particular manner of imparting the necessary low degreeof temperature to these chambers, as this may be done in any suitableway, and various changes might be made in the general form andarrangement of parts described without departing from my invention, andhence I do not limit myself to the precise details set forth, butconsider myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of the appended claims.
